Aims: This study discusses the model built to explore low levels of communal traits’ influence on nurses’ stay intent. Background: The high turnover rate and low stay intent amongst Taiwan's nurses is a serious issue. One reason for the low stay intent is nurse-to-nurse interpersonal conflict. Surface-level difference, such as low levels of communal traits, may be an important antecedent factor. Previous studies have found that this type of conflict can frequently arise in female-to-female relationships. Design: This was quantitative, cross-sectional research using a questionnaire survey. Method: 249 registered nurses participated in the survey, which employed convenience sampling. The data was collected from January 10th 2020 to February 10th 2020. Results/Findings: We found that nurses with low levels of communal traits become frustrated, creating psychological need thwarting and decreasing stay intention. Belonging perception appears to weaken this. In addition, autonomy and relatedness of need thwarting but not competence mediates the relationship between frustration experience and stay intent. Unlike in past studies, this was not found to be an exclusively female phenomenon. Conclusion: Improving belonging perception may be the answer to overcoming negative outcomes caused by surface-level difference in the nursing profession. However, why surface-level difference has a negative influence remains a question that needs to be further explored. In addition, Taiwanese nursing managers in this low status and relationship-oriented nursing culture should also focus on improving frontline nurses’ confidence and self-conceptualizations.
